A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Rhodonite is a manganese silicate mineral (often with iron, magnesium and calcium) known for its pink to rose-red color, commonly with black veins or patches of manganese oxides. It occurs in massive, granular and occasionally transparent crystal forms. With Mohs hardness about 5.5–6.5 and good toughness, it is suitable for cabochons, beads and carvings; transparent crystals are rare and mostly of collector interest.
